ABSTRACT:
Toner particles of an intimate mixture of 25 to 75% by weight of substantially colorless, inert, nonelectroscopic spheroidal-shape polymer particles of size distribution in the range of greater than 5 to less than 60 .mu.m, not more than 15% of the polymer particles being less than 10 .mu.m or greater than 50 .mu.m equivalent spherical diameter, and 75 to 25% by weight of colorant particles having a size distribution within the range of 0.2 to 30 .mu.m and not more than 50% of the colorant particles being less than 1 .mu.m particle size. Ionic copolymer spheroidal particles are preferred. The toner particles are useful for color development of tacky areas by depositing and distributing the toner particles by means of a pad, including an applicator apparatus comprising a housing for toner, a free moving weight in the housing for agitating the toner, means to release toner from the housing, and at least two hinged pads mounted on the housing.
